Fallout 3 Part 1

Believe it or not I prefer this one over New Vegas. Don't care at all about 4 or 76. Classics are the best Fallout games, but different because combat and camera. Anyways I like FO3's open hostile world. Random Events add some flavor to the local area you are exploring and multiple different factions can appear in interesting areas. Many interesting buildings to explore. I like the dark metro systems but most people hate them. New Vegas proper is cool, but I like the DC zones because it's a shipwreck graveyard of free exploration while everything around wants to kill you.
New Vegas is great also. I just wish it had more hostile environs to explore. In NV there's a NCR or Legion outpost at every corner. Too much talky, not enough adventure/explore on your own terms. Boulder City for example could be a large Raider base or Mutant base. Instead it's another side quest area with main story NPCs/factions where you don't want hostilities with anyone.. yet. No Random Events anywhere. While NV is praised for it's superior dialogue it can't compare to the classics that were made before mass sanitation Western censorship. NV dialogue/writing is better than FO3's childish writing for sure though.

42:20 - You can save the two siblings. Have to rush the two pistol guards and kill them first. Determines the siblings fate if they are around or not in a future side mission. There are many subtle changes depending on your actions during the Vault Escape to coming back later for Trouble on the Homefront.
